What Carbon Limit does
Carbon Limit Co. is a Boca Raton, Florida-based climate tech company founded in 2020–2021 that develops proprietary concrete admixture technologies to reduce the carbon footprint of cementitious construction materials. Its flagship product, CaptureCrete®, is a dry powder admixture made from a proprietary blend of natural aluminosilicates and reactive oxides that is dosed at 0.5%–1.5% of cementitious content (or up to 7% as admixture, or up to 30% as a supplementary cementitious material replacing cement) and approved under ASTM C-494 and AASHTO M-494 as a Type-S Admixture. CaptureCrete® enables up to 15% higher 28-day compressive strength, up to 12% cement reduction, and up to 100 kg of permanent CO2 sequestration per ton of concrete via mineralization, with potential total CO2 footprint reduction of up to 75%. In September 2024 the company launched CoolCrete™, a heat-reducing SCM that lowers concrete surface temperatures by up to 10°C at peak conditions and cuts concrete's carbon footprint by up to 40%.
Carbon Limit monetizes through three streams: (1) technology licensing and admixture sales to ready-mix concrete producers, OEMs, and concrete product manufacturers (deployments include Minnesota DOT, Titan America, Google data center, NCP Industries, and Bison Innovative Products); (2) Verra VCS-certified carbon credit sales under project VCS 3918 using the VM0043 methodology, offering Avoidance Credits and Blended Credits; and (3) grant and pre-seed funding, including a $740K U.S. EDA Tech Hub award and a $100K Shopify purchase through AirMiners. The go-to-market combines direct enterprise sales, a five-step structured onboarding process (planning, testing, results review, digital integration, post-sale support), and an OEM/white-label licensing model that embeds CaptureCrete® and CoolCrete™ into licensee product lines. The company employs 11–50 people and is led by founder/CEO Tim Sperry, with senior executives recruited from CarbonCure Technologies, Sysdyne Technologies, GCP Applied Technologies, and other specialty construction chemicals firms.

Revenue model
- Technology Licensing: Carbon Limit licenses its CaptureCrete® and CoolCrete™ technologies to concrete producers, manufacturers, and product companies. Licensees (such as NCP Industries and Bison Innovative Products) incorporate the additives into their products and pay licensing fees. The technology is designed as a drop-in additive requiring no additional equipment, making adoption straightforward for licensees.
- Carbon Credits Sales: Carbon Limit issues and sells high-quality carbon credits (avoidance and blended credits) to businesses and communities seeking to offset their carbon footprint. The credits are tied to the deployment of CaptureCrete® by ready-mix concrete producer partners. Credits are verified under the Verra VCS program using the VM0043 methodology, with proceeds shared with concrete producers.

Carbon Limit product offering
Product offeringCore offering
Carbon Limit develops proprietary concrete admixtures, including CaptureCrete® and CoolCrete™, that chemically capture and permanently store CO₂ within cured concrete while reducing required cement content. The Boca Raton-based company licenses this chemistry to ready-mix and precast concrete producers and monetizes the associated CO₂ removal by issuing Verra-certified carbon credits.
Product overview
Carbon Limit offers a portfolio of sustainable concrete additive technologies centered on two main products: CaptureCrete® (a CO2-capturing concrete additive available as admixture and SCM forms) and CoolCrete™ (a heat-reducing additive). Both products integrate into existing concrete production without requiring new equipment. The company also offers a Carbon Credits program that enables concrete producers to generate and sell carbon credits tied to CaptureCrete® deployment, creating additional revenue streams for customers.

Carbon Limit competitors and assessment
Company assessmentBroad incumbents
- Holcim: Holcim is one of the largest global cement and ready-mix concrete producers with extensive low-carbon concrete product lines. As both a potential customer (deploying third-party additives) and competitor (own in-house ECOPact and Airium technologies), it is materially comparable.
- Master Builders Solutions (BASF): Master Builders Solutions, part of BASF, is one of the largest global concrete admixture and cement-additive businesses. Its portfolio overlaps directly with CaptureCrete and CoolCrete use cases, and it competes for the same ready-mix producer customers.
- CarbonCure (parent reference) / Sika AG: Sika is a global leader in concrete admixtures and specialty chemicals for construction. As a broad incumbent offering a wide portfolio of Type-S and Type-F admixtures, it represents both a competitor and a potential acquirer of single-product players like Carbon Limit.
- Heidelberg Materials: Heidelberg Materials is a major global cement producer with growing low-carbon and CCUS initiatives. It is comparable both as a potential CaptureCrete licensee and as a vertically integrated competitor developing its own carbon-cured and low-carbon concrete solutions.
- Chryso (Saint-Gobain): Chryso, part of Saint-Gobain, supplies admixtures, additives, and decorative solutions for the concrete industry. Its broad admixture portfolio competes with Carbon Limit at the ready-mix producer level and represents a comparable channel into the same customer base.
Emerging players
- CarbonOrO: CarbonOrO is an emerging European player that injects CO2 directly into fresh concrete to permanently mineralize it. It is comparable in mechanism and target customer to Carbon Limit, though its geographic focus differs.
- Carbon Upcycling Technologies: Carbon Upcycling converts CO2 emissions into additives for concrete and other materials. It targets a similar CO2-to-concrete value proposition and competes for the same ready-mix and cement producer customers, though at an earlier commercial stage.
- Brimstone (Carbon-negative Portland cement): Brimstone is developing carbon-negative Portland cement from industrial silicates, targeting the same cement decarbonization market as Carbon Limit but at the binder level rather than as an admixture. It competes for downstream decarbonization budgets and ESG mandates.
Direct peers
- Solidia Technologies: Solidia uses CO2 curing to produce lower-carbon concrete and cement-based products, addressing the same decarbonization pain point as Carbon Limit but through a curing-based approach rather than an admixture. It is a direct comparable in concrete CO2 utilization.
- CarbonCure Technologies: CarbonCure is the leading direct competitor in CO2-mineralizing concrete admixtures. It sells CO2-injected ready-mix technology to ready-mix producers and has hundreds of systems installed globally, making it the canonical comparable for Carbon Limit's CaptureCrete value proposition.
